Quick Answer
Skinfold Body Fat helps you quantify body measurements and interpret trend direction in a practical way.
How to Calculate Skinfold Body Fat
- Enter your measurements.
- Click Calculate.
- Review the value and interpretation.
- Track changes every few weeks.
Formula
Body density (male) = 1.10938 - 0.0008267 x sum + 0.0000016 x sum^2 - 0.0002574 x age
Body density (female) = 1.0994921 - 0.0009929 x sum + 0.0000023 x sum^2 - 0.0001392 x age
Body fat % (Siri) = (495 / density) - 450
Worked Examples
Example 1
Example: male, age 30, skinfolds 12/16/18 mm gives body fat around the high-teens depending measurement precision.
Example 2
Try a higher-input scenario than Example 1 to test sensitivity. A larger output can move the result into a higher interpretation range, which helps with planning and monitoring.
Example 3
Try a lower-input scenario than Example 1 to set a baseline target. Compare this result with your current values and track trend direction over time.
